BABYS FIRST YEAR intellectual Development Neuron Model Dendrites
BABY’S FIRST YEAR intellectual Development
Neuron Model Dendrites Cell Body Axon Synapse – can be drawn as a circle on the end of the neuron
Parts of a neuron CELL BODY - center of the neuron AXON - connection between neurons that transmit (SEND) instructions from cell body to other neurons DENDRITE - branch-like feature at end of axons that RECEIVE electrical messages from other neurons MYELIN - fatty, insulating substance that helps transmit info faster from one nerve cell to another SYNAPSE - tiny gap between dendrites where messages are transmitted from one neuron to another
v connections How the brain becomes organized between dendrites and axons link groups of neurons together (system) v groups (systems) then control certain actions vbranching – new connections formed from having new experiences vpruning – fading away of pathways (connections) when a behavior is not repeated/used v. BOTH happen throughout life
Intellectual DVLP va baby’s 5 senses are the building blocks of learning perception - ability to learn from sensory information vperception improves as experiences are repeated
4 Signs of Intellectual Growth 1. remembering experiences vcan begin to anticipate what will happen next based on past experiences vdevelops during first few months 2. making associations vlink people to experiences
3. understanding cause & effect vone action results in another action vas baby gets older, understanding increases of their own power to make things happen 4. paying attention vattention span lengthens as babies get older vlack of attention may mean a baby is bored
Periods of Learning v. Sensorimotor Period v. Birth – 2 yrs old vbabies learn through their 5 senses and their own actions vobject permanence vconcept that an object will continue to exist even if it is out of sight vdevelops around 10 months old
Developing Communication vone of the major tasks of infancy is to learn to communicate with others vhealthy babies should show steady improvement in communication skills
Nonverbal Communication vbabies can communicate long before they can talk vcrying gestures & movements vfacial expressions v
Verbal Communication vbabies must learn to associate meanings with words vbegin with “babbling” – repeated consonant/vowel sounds vfirst “real” words usually understandable between 8 & 15 months vcannot combine words into sentences until after first birthday
Bellwork #10 v. Review: What are options for parents when they feel they cannot handle a baby’s uncontrollable crying?
Bellwork #11 v. Use chart in text on pg. 270 to answer: What is the name of the period of learning that lasts from birth– 2 yrs old? vsensorimotor period
Bellwork #12 v. Review: Draw and label the following parts of a neuron: cell body, synapse, dendrites, axon.
